John 2:18-22

18The Jews then said to him, What sign can you show us for doing this?
19Jesus answered them, Destroy this temple, and in three days I will raise it up.
20The Jews then said, This temple has been under construction for forty-six years, and will you raise it up in three days?
21But he was speaking of the temple of his body.
22After he was raised from the dead, his disciples remembered that he had said this; and they believed the scripture and the word that Jesus had spoken.
